SAFE oons'rnno'rron.

Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed November 25, 1914. Serial No. 873,875.

To all whom it may concern:

Be it known that we, Mosns MOSLER, a citizen of the United States, residing at Cincinnati, Hamilton county, Ohio, and hum BARTELS, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Safe Construction, of which the following is a specification.

This invention, pertaining to safe-construction, and in referring to safes we intend the comprehension of vaults as well, relates to the system by means of which the door of the safe is drawn tightly to its seat in the jamb when the door is being closed and forced out of the seat in the j amb when the door is to be opened, the mechanism-for accomplishing these results serving as a pressure-bar device for forcing the door to and away from its seat in the amb or, if clesired, serving also as means for locking the door of its seat.

Our invention will be readily understood from the following description taken in connection with the accompanying drawings in which z- Figure 1 is a front elevation of the front of the safe with the door closed, the upper left-hand corner of the door being broken entirely away to expose jamb-features, and the lower portion being shown in vertical section in the plane of line Z) of Figs. 2, 4 and 5. Fig. 2, a vertical section of the structure in the plane of line a; of Figs. 1 and 3, the major portion of the edge of the door appearing in elevation: Fig. 3, a front elevation of a portion of the system of toothed bars carried by the door: Fig. 4, a horizontal section of the door-jamb and door in the plane of line 0 of Figs. 1, 2, 3 and 5, the door being shown separated from the jamb but'in position to be pushed into the jamb: Fig. 5, an elevation'of the teeth in the jamb at the left side of Fig. 1 and viewed from the right in Fig. 1, combined with a vertical section of the cooperating locking teeth of the door, the section being taken in the plane of line (i of Figs. 1, 3 and 4, the locking teeth of the door being in position corresponding. with the unclosed condition of the door, that is to say, the door is yet to be closed into its jamb by a motion in the direction of the arrow 2', the same as in Fig. 4; and Fig. 6, a plan of the toothed locking .bar carried by. the left-hand edge of the door. Diverse scales are employed in the drawings.

In the drawings: 1, indicates the front of the safe; 2, the stepped door-opening therein; 3, a toothed bar rigidly secured in the jamb, there being one of these bars at each margin of the jamb, the bar being provided at intervals with inwardly projecting teeth, the bar being merely an eXpedience for se curing the teeth in the jamb; 4, the door; 5, the stepped margin of the door adapted to tightly fit the amb; 6, hinge-bearings upon the door and safe, adapted to receive the usual crane-hinge; 7, a groove in each of the marginal edges of the door and extending the general length of the margins, though not necessarily connecting at the corners of thedoor; 8, a toothed-bar fitted to slide in each of these marginal grooves and prevented from displacement therefrom by any suitable means, slots and cross-pins being illustrated for the purpose, each of these bars being provided at intervals with outwardly projecting teeth adapted to pass through the spaces between the teeth of the amb when the door is being closed; 9, a shive mounted at each corner of the door in the plane of these toothed bars; 10, chains passing over these shives and connecting the contiguous ends of bars 8 in such manner that when one of the bars is shifted endwise, a corresponding endwise shifting of all the other bars must take place; 11, a rack provided on the inner edge of one of bars 8, preferably the edge farthest from the hinge-bearings carried by the safe front; 12, a spindle journaled in the door near the rack and accessible from the front of the door, so that it may be turned; 13, a pinion on the rear end of these spindles, engaging the rack on the toothed bar; 1%, a pivoted locking-dog mounted near pinion 13 and having a toe normally out of engagement with the pinion but adapted to engage a shoulder on the periphery of the pinion and prevent the pinion from turning in a certain direction; 15, a lock-connection from the locking-dog and adapted to be connected in any suitable manner with the lock or looks of the door, regardless of whether the locks be combination looks or time looks or both; 16, the knobs of usual combination locks on the door, to serve in controlling the locking-dog; 17, the inwardly projecting locking teeth of the j amb; 18, the outwardly projecting locking these hooks being opposite jamb-hooks 21,

and 23, bevels on the front corners of some of the door-teeth and on the rear corners of cooperating ones of the jamb-teeth, these bevels being in the same direction as the bevels upon the front of the door-teeth and upon the rear of the jamb-teeth, but at greater angle.

Generally stated, when the door is pushed into its jamb the teeth 18 of the door pass through the spaces between the teeth 20 of the jamb and take position to their rear,

after which spindle 12 is turned causing a simultaneous endwise movement of all of the door-bars 8 thus causing the door-teeth to slide behind the jamb-teeth, the cooperating bevels on these. teeth drawing the door solidly to its seat in the jamb. The safelooks whatever be their character may cause dog 14: to lock the pinion so as to prevent releasing movement of the door-teeth. Under these conditions the system would have acted as a pressure device to force the door solidly to its seat, and as a locking device to prevent the door being unseated.

In all of the figures of the drawings the door-teeth are indicated in unlocked position, that is to say, while the door has been pushed to closed position, it may be freely.

opened. In Fig. 5 and in F ig. 4 the door elements are indicated as not yet having entered the jamb. Looking at Fig. 5, under stand that teeth 18 are sliding teeth carried by the door. Upon pushing the door to the right as indicated by arrow 2' the doorteeth 18 will pass between the Jamb-teeth 1'? and take position to their rear. This motion will be arrested when the bevels'of the doorhooks 22 strike the bevels of jamb-hooks 21. When this occurs, still looking at Fig. 5, the

' door-teeth mustmove downward somewhat,

which motion brings bevels 28 in engagement and forces the door farther into its jamb, with quickness but not powerfully. A continued downward motion of the doorteeth causes their'bevels 19 to cooperate with the bevels 20 on the amb-teeth, thus forcefully seating the door solidly in the jamb, and locking thedoor to the jamb if the toothed door-bars be under the control of the safe-locks, Stilllooking at Fig. 5, when the safe is tobe opened, the toothed door-bar is raised, the safe locks, if in action, having been first released; The first efiect of the rising of door-teeth 18 is to release the pressure between bevels 19 and 20, without necessarily unseating the door from its jamb. But when the rising motion of the doorteeth causes the bevels of door-hooks 22 to engage the bevels of jamb-hooks 21, then the door becomes forced away from its seating in the amb and, the upward motion of the door-teeth having been completed, the door is at liberty to be opened.

Looking at Figs. 1 and 3, indicating the door-teeth 18, as in released condition, the turning of pinion 13 in counter-clockwise direction will move the left-hand toothedbar in the direction of arrow 0, the lower toothed-bar in the direction of arrow 7 the right-hand toothed-bar in the direction of arrow 9 and the top-bar in the direction of arrow h. By this motion of the bars, carried to the proper extent, the door has been forced solidly to its seat. If, now, the safelocks be put on duty, the locking-dog 14 prevents the retracting motion of the pinion and the door is not only solidly seated in its jamb, but is locked.

In the illustrated example the toothedbars of the door are provided with teeth at short intervals. There may be as many of these teeth as desired, for purposes of tightseating of the door and for purposes of security, the thinner the door the greater being the desirability for a number of the teeth disposed along intermediate portion of the door-bars, with, of course, corre sponding teeth in the jamb. But it is obvious that the door-bars may have teeth near their ends only, their intermediate portions being toothless and correspondingly as to the teeth in the jamb. For instance, looking at Fig. 5, the door bar might, if desired, be provided at its upper end with only the hooked tooth, and the jamb with only the hooked tooth and the tooth below it. In such case there would be produced the result of urging the door to its jamb, and then forcing it solidly to the jamb and locking the door in its jamb and, when the door was to be opened, forcing the door out of its seating in the j amb.
